Definitions

  • the internally mounted antennas may typically be provided as printed circuit antennas.
  • Two techniques frequently employed in this respect are screen-printing and tampon printing. While such techniques are simple and cost effective they are not very flexible since the antenna patterns to be produced have to be determined at an early stage in the production process. Further, they are difficult to use for the production of antenna patterns onto curved surfaces, particularly concave surfaces, if at all possible.
  • Another object of the present invention is to provide a process for mass producing printed circuit antennas, which minimizes the time required to produce such printed circuit antennas.
  • FIG. 2 d illustrates, schematically, a particular embodiment of the system for producing an antenna device as illustrated in FIG. 1 .
  • the system 1 further comprises a carrier 15 in the form of a bench, worktable, or similar, and a means 16 , such as for example a frame or support, for interconnecting ejecting apparatus 3 and carrier 15 in accurately and precisely controlled fashion and for moving the carrier 15 and ejection opening 5 of ejecting apparatus 3 relative each other in a plane substantially perpendicular to the direction of the jet 13 ejected from opening 5 .
  • a carrier 15 in the form of a bench, worktable, or similar
  • a means 16 such as for example a frame or support, for interconnecting ejecting apparatus 3 and carrier 15 in accurately and precisely controlled fashion and for moving the carrier 15 and ejection opening 5 of ejecting apparatus 3 relative each other in a plane substantially perpendicular to the direction of the jet 13 ejected from opening 5 .
  • the solidification of the antenna pattern may be speeded up by means of heating the liquid conductive substance ejected onto the dielectric substrate; or by means of blowing a gas, particularly dry air, over the dielectric substrate and the liquid conductive substance ejected thereon.
  • Such dual antenna pattern may be produced to enhance the RF performance of the antenna device, to allow for multiband operation and/or to form electrical circuits, e.g., matching circuits including capacitors, directly on the dielectric substrate 21 .
  • the liquid conductive substance is conductive ink and the ejecting apparatus is an ink jet printer.
  • FIGS. 2 a and b showing the basic structure of an ink jet printing device for safe, rapid and reliable ejection of droplets of a conductive ink, wherein droplet formation is achieved by means of thermal energy.
  • Ink is supplied from an ink supply tank 38 maintained under a predetermined elevated pressure P 3 to a printing channel 35 via a conduit 37 .
  • the printing channel 35 can be a capillary channel similarly ensuring reliable ink feed from a tank towards a printing opening 39 .
  • the printing channel 35 is formed by means of a base plate 34 and a cover plate 36 provided with an appropriate groove.
  • the resistor 33 can be covered by a thermoconductive foil (not shown), which is in close contact therewith and which protects the resistor against thermal burnout into the ink. Moreover, such foil makes the resistor insensitive to the chemical properties of the ink used.
  • ink jet printing device for use in the present invention has been described in two embodiments by way of example it shall be appreciated that the same can be varied in a plurality of ways. Such further variations regarding ink jet printers and ink jet printing technologies may be found in U.S. Pat. Nos. 4,050,075 issued to Hertz et al. and U.S. Pat. No. 6,155,680 issued to Belon et al., and in references therein, all of which being hereby incorporated by reference.
  • antenna patterns may be formed on essentially non-planar surfaces such as curved, convex and concave surfaces and still maintain a substantially constant distance between the opening of the printing head and the non-planar surface on which the antenna pattern is to be formed.
  • a dielectric substrate 21 having an essentially non-planar surface on which the antenna pattern is to be formed, is mounted at table 63 , whereafter table 63 is moved in the XY-plane and in the Z-direction while ejecting liquid conductive substance from printing head 60 .
  • the movement in the XY-direction is indicative of the antenna pattern to be produced and the movement in the Z-direction is performed to follow the non-planar surface of the dielectric substrate 21 , i.e. to obtain a constant distance to the non-planar surface of the dielectric substrate 21 during production.
  • the movement in the Z-direction is thus performed to keep the opening of printing head 60 on a level with dotted line 66 .
  • FIG. 3 a shows an antenna device comprising a meander pattern 71 produced on a dielectric substrate 21 , for instance a stiff or a flexible substrate.
  • a dielectric substrate 21 for instance a stiff or a flexible substrate.
  • Using a flexible substrate enables the shape of the substrate to be adapted to the shape of the casing of the portable radio communication device in which it is to be mounted.
  • the meander shaped antenna pattern 71 has a feed connection point 72 and a number of parallel feed and ground lines 73 , all connected to a feed point 72 and a ground point 74 via a common main feed line 75 and a ground line 76 , respectively.
  • the antenna element also comprises additional capacitive components 77 and an inductive component 78 connected to ground.
  • the dotted lines 79 illustrate some positions where the length of the antenna pattern 1 can be adjusted.
  • the reference numerals 80 designate short circuiting lines between different points of the antenna element.
  • the capacitive and inductive components 77 , 78 are illustrated as discrete components. However, the desired capacitance or inductance can easily be provided by means of suitable formed conductive path. of the same kind as the conductive path of the antenna element and applied on the same substrate as the antenna element and connected thereto, as is known in the art.
  • FIGS. 3 c and d illustrate, schematically in cross-sectional views, two further antenna patterns as produced according to production methods of the present invention.
  • the conductive ink layer 91 is provided so that a plated metal layer 92 adheres satisfactorily thereto.
  • the conductive ink layer 23 is selectively chemically plated with a metal layer 92 of a conductive metal such as nickel or copper such that the plated metal layer 92 obtains a pattern substantially matching pattern 91 and overlying the same.
  • adhesive in the conductive ink is etched away from the conductive ink layer 91 to make the surface thereof rough, the rough surface of the ink layer 92 is then chemically plated with a conductive metal such as nickel or copper in the presence of a catalyst such as platinum.
  • FIG. 4 is a flow scheme of an iterative production process, a further embodiment of the present invention will be described.
  • the dielectric substrate with said antenna pattern formed thereon and the portable radio communication apparatus of the particular model are disassembled wherein the antenna pattern is electrically disconnected from the RF feed device of the portable radio communication apparatus.
  • the measured antenna characteristic is, in a step 109 , used in a decision model to decide on whether the characteristic is acceptable, if it is not fully acceptable but indicate that it could be acceptable subsequent to certain modification of the antenna pattern, or not all acceptable.
  • the dielectric with the antenna pattern is sorted according to the taken decision: if the characteristic is acceptable the dielectric with the antenna pattern is approved as a produced antenna device, if it is not at all acceptable the dielectric with the antenna pattern is rejected, and if the dielectric with the antenna pattern is to be modified it is, in a step 113 , returned to the ejecting apparatus such that, again in a step 101 , a further modified conductive antenna pattern can be formed on the dielectric.
  • the process then continues with the steps 103 - 111 until the dielectric with the antenna patterns or modified antenna pattern ultimately will be approved or rejected.
  • components 73 , 77 , 78 , pattern length at 79 , and 80 of the antenna pattern illustrated in FIG. 3 a and components 87 and 88 of the antenna pattern illustrated in FIG. 3 b are examples of additional structure that can be applied to an initially formed antenna pattern.
  • dotted circles 81 in the antenna patterns of FIG. 3 a and b can indicate positions where electrical paths are disrupted by means of removing antenna material.
  • the production process described above can be applied in the initial phase of the mass production of a particular antenna device.
  • the ultimately approved antenna device with the modified antenna pattern can used as a template for the mass production of antenna devices for use in portable radio communication apparatus of the particular model.
